#include <mlib.h>

mlib_status mlib_SignalIIR_P4_S16_S16_Sat(mlib_s16 *dst, 
    const mlib_s16 *src, void *filter, mlib_s32 n);

mlib_status mlib_SignalIIR_P4_S16S_S16S_Sat(mlib_s16 *dst, 
    const mlib_s16 *src, void *filter, mlib_s32 n);

mlib_status mlib_SignalIIR_P4_F32_F32(mlib_f32 *dst, 
    const mlib_f32 *src, void *filter, mlib_s32 n);

DESCRIPTION

Each of these functions applies a fourth order parallel IIR filter to one signal packet and updates the filter state.

Printed copy or docs.sun.com displays an equation that represents the fourth order parallel IIR filtering.

The fourth order parallel IIR filter is represented by the following figure:
